Code :

public List ScriptCmnd(string s)
        {

            si.StartInfo.Arguments = s;
            si.Start();
            string output = si.StandardOutput.ReadToEnd();
            List result = output.Split(''\n'').ToList();
            si.Close();
            return result;
        }

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
        {
            if ( e.Node.Level != 0)
            {
                string removeStr = "Project.pj";
                List result = ScriptCmnd("/c si viewproject --no --fields=name --project=''" + e.Node.Name);
                result.RemoveAll(x => x == "" || !(x.Contains("project.pj")));
                if (result.Count != 0)
                {
                    foreach (string sr in result)
                    {
                        TreeNode trChild = new TreeNode();
                        trChild.Text = sr;
                        trChild.Name = e.Node.Name.Remove(e.Node.Name.IndexOf(removeStr, StringComparison.OrdinalIgnoreCase), removeStr.Length) + sr;
                        
                        treeView1.SelectedNode.Nodes.Add(trChild);
                        treeView1.SelectedNode.ExpandAll();
                    }
                }
            }
        }
